APPRIS ALT2: For genes in which the APPRIS core modules are unable to choose a clear principal isoform, the ALT1 is the candidate transcript(s) models that appear to be conserved in fewer than three tested species.

APPRIS is a system to annotate alternatively spliced transcripts based on a range of computational methods to identify the most functionally important transcript(s) of a gene.

APPRIS ALT1: For genes in which the APPRIS core modules are unable to choose a clear principal isoform, the ALT1 is the candidate transcript(s) models that is conserved in at least three tested species.

APPRIS is a system to annotate alternatively spliced transcripts based on a range of computational methods to identify the most functionally important transcript(s) of a gene.

APPRIS P4: Where the APPRIS core modules are unable to choose a clear principal CDS and there is more than one variant with a distinct (but consecutive) CCDS identifiers, APPRIS selects the longest CCDS isoform as the principal variant.

APPRIS is a system to annotate alternatively spliced transcripts based on a range of computational methods to identify the most functionally important transcript(s) of a gene.
